The Grand Canyon is America's busiest wonder. Mather's 327 sites sell out in minutes. Dibs on Dirt monitors Recreation.gov nonstop. We email you the moment a site opens.
Get Alerts FreeNearly 5 million visitors descend on the Grand Canyon every year, and unlike seasonal parks that go quiet in winter, the year-round South Rim keeps demand constant. Every month is peak month for someone.
Mather Campground's 327 sites book the moment reservations open six months out on Recreation.gov, and most sought-after dates are gone within minutes of release. Desert View Campground, 25 miles east along the rim with 50 sites and unobstructed canyon views, is equally gone as soon as it opens.
Cancellations hit Recreation.gov in real time. Dibs on Dirt monitors both Mather and Desert View continuously so you don't have to keep a browser tab open and a prayer going — you'll get an email the instant something opens in your window.
